Question

我在iPhone应用中使用Youtube API v3.0，并且我已经使用Google plus API处理了YouTube授权。现在我需要按照链接中的示例订阅youtube频道..

https://developers.google.com/youtube/v3/docs/subscriptions/insert#examples

所以在我的代码中..

NSString *URLString = [NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&key=%@", API_KEY];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];

[requestSerializer setValue:[AOTube accessToken] forHTTPHeaderField:@"Authorization"];
[requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

manager.requestSerializer = requestSerializer;

NSDictionary *parameters = @{@"snippet":@{
                                     @"resourceId":@{
                                             @"channelId":CHANNEL_ID,
                                             @"kind":@"youtube#channel"
                                             }
                                     }
                             };

[manager POST:URLString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

    success(responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    failure(error);

}];

我从失败块中收到以下错误..

我确定API_KEY，CHANNEL_ID和访问令牌没有任何问题，因为我已经成功地在其他网络服务中使用它们

您没有正确设置授权标头字段。

而不是：

[requestSerializer setValue:[AOTube accessToken] forHTTPHeaderField:@"Authorization"];

使用：

NSString *authValue = [NSString stringWithFormat:@"Bearer %@", [AOTube accessToken]];

[requestSerializer setValue: authValue forHTTPHeaderField:@"Authorization"];

接下来将您的请求序列化程序更正为：

AFHTTPRequestSerializer *requestSerializer = [AFJSONRequestSerializer serializer];

在授权过程中，添加以下至少一个范围：https://www.googleapis.com/auth/youtubepartner或https://www.googleapis.com/auth/youtube

样品：

signIn.scopes = @[ kGTLAuthScopePlusLogin, @"https://www.googleapis.com/auth/youtube" ];

如果使用Google API正确签名，则不必在URL中包含API密钥请求参数。
